Relativistic Time Delay from Viking Relativity Experiment. VOL. 82. NO. 28 JOURNAL OF GEOPHYSICAL RESEARCH SEPTEMBER 30. ]977
Arecibo Observatory 305 m (1,000 ft) radio telescope is the largest single-aperture telescope built between the summer of 1960 and November, 1963
Light Deflection and Time Delay Experiments • http://arxiv.org/PS_cache/gr-qc/pdf/0103/0103036v1.pdf - Clifford Will - The Confrontation between General Relativity and Experiment, March 2001 • Figure 5: Measurements of the coefficient (1+γ)/2 from light deflection and time delay measurements. General relativity value is unity. Arrows denote anomalously large values from early eclipse expeditions. Shapiro time-delay measurements using Viking spacecraft yielded agreement with GR to 0.1percent, and VLBI light deflection measurements have reached 0.02 percent. Hipparcos denotes the optical astrometry satellite, which has reached 0.1 percent.
